Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85816, here are decompositions:

23 + 85793 = 85816
83 + 85733 = 85816
113 + 85703 = 85816
149 + 85667 = 85816
173 + 85643 = 85816
197 + 85619 = 85816
239 + 85577 = 85816
293 + 85523 = 85816

Showing the first eight; more decompositions exist.
